Definitions

  • each section has one or more upwardly open blank molds for receiving the gob, or groups of gobs and a baffle is adapted to move in and close the open end of the blank mold in order to permit the gob to be pressed or otherwise formed from below in order to form an inverted parison at the blank station.
  • This inverted parison is transferred or swung over to the blow side of the section where it assumes an upright orientation in a finishing mold.
  • a blow head descends onto the top of the finishing mold and the parison is blown to its final shape while the transfer mechanism returns with the neck ring mold in order to form another parison or parisons.
  • the parison transfer mechanism in each of the individual sections of such a machine comprises two neck ring arms mounted in an axially split neck ring mechanism or hub structure, which structure includes means for rotating these arms through approximately 180°.
  • the neck ring mold halves are mounted at the free ends of these arms and when the parison has been formed at the blank station the still closed neck ring mold halves serve to clamp the newly formed parisons therebetween as the neck ring arms move from the inverted parison position at blank station, to an upright position at the blow station.
  • the neck ring arms Once positioned in the finishing mold, the neck ring arms move apart slightly, by axial movement of the associated arms, to release the parison and permit the arms and the neck ring molds to return to the blank side of the machine.
  • the principle aim of the present invention is to adapt a glassware forming machine section of the foregoing type in order to permit forming of the parison in an upright configuration, and for transfer of the parison to the blow side of the machine while maintaining this upright orientation.
  • the blank station In adapting a conventional Hartford I. S. type glassware machine to the formation of upright parisons at its blank side, and to provide for transfer of these upright parisons to the blow side of the machine, the blank station has at least one upwardly open blank mold cavity defined by a body mold, which body mold may be of the solid type, and also at the blank mold station an intermediate mold is provided which may be of the split type and mounted on the existing blank mold holder arms.
  • the neck ring arms pivotally support the neck ring structure adjacent the free ends thereof, and a hub structure pivotally and slidably supports the other ends of these arms for movement between the blank station and the blow station, and for movement toward and away from one another so as to permit releasing of the parison at the blow side of the machine section.
  • means is also provided for mechanically driving at least one of the neck rings molds structures as the arm is moved between said stations whereby the parison and neck ring structure remain in a predetermined orientation with respect to the fixed frame of the machine during transfer.
  • FIG. 1 is a side elevational view of the relevant portions of an individual glassware forming machine section with certain movable parts being shown in broken lines to illustrate alternative positions for such parts.
  • FIG. 2 is a plan view of the glassware forming machine section depicted in FIG. 1, with a portion of the neck ring structure broken away.
  • FIG. 3 is a vertical sectional view taken generally on the line 3--3 of FIG. 2, but showing the parison forming plungers inserted into the blank mold defining structure at the blank station, and also showing in schematic fashion the conventional timing means used to operate the various fluidic devices or components of the typical glassware forming machine.
  • FIG. 3 shows the blank side or station of a glassware forming machine of the Hartford I. S. type wherein one or more gobs of molten glass are adapted to be delivered into the upwardly open blank mold cavities through the medium of fixed chutes 10 and 12 associated with each of the cavities in the blank mold structure.
  • the plunger mechanism indicated generally at 14
  • the plunger mechanism would be positioned in its inactive position as best shown in FIG. 2 in order to permit the gobs of molten glass to be dropped into the upwardly open blank mold structure.
  • a funnel mechanism indicated generally at 16 is adapted to be swung inwardly over the upwardly open blank mold cavities for guiding these gobs of glass as they are dropped downwardly from their associated chutes 10 and 12 into the blank mold structure.
  • the blank mold structure illustrated in FIG. 3 may be similar to that shown and described in my issued U.S. Pat. No. 3,765,862. That is, the blank mold structure may include a relatively wide cavity lower body mold, a relatively narrow neck ring mold structure, and an intermediate or transitional mold which is placed between the neck mold and the body mold so that the parison can be formed.
  • the transitional or intermediate mold is split, the two halves being mounted to the conventional blank mold holder arms provided in a Hartford I. S. type machine.
  • the intermediate mold halves open after the parison has been formed to permit the parison to reheat and stretch, the body molds being dropped, or retracted downwardly slightly, so that even before transfer takes place a segment of the cycle is devoted to reheat at the blank station.
  • the relatively wide cavity body mold or molds are depicted at 18 and 20, and a fluid motor in the form of an air cylinder 22 is provided for raising and lowering these solid body molds 18 and 20.
  • the intermediate or transitional molds 24 and 26, associated with these body molds 18 and 20 respectively, are mounted to the blank mold holder arms best shown in FIG. 2 at 28 and 30.
  • These intermediate molds 24 and 26 are of the partible type, being mounted in pairs to the mold holder arms 28 and 30 in a conventional manner.
  • a hinge pin 32 is provided in the fixed frame of the machine and these mold holder arms 28 and 30 are pivotally supported thereby, and are adapted to be operated in timed relationship with other components of the machine through conventional mold holder arm moving links (not shown).
  • the neck ring portions of the blank mold defining structure comprises split or partible neck ring molds segments 34 and 36, which neck ring mold halves or segments are also provided in pairs, and are preferably mounted in a cartridge structure best illustrated in FIG. 2 at 38 and 40.
  • the blank mold structure of FIG. 2 is of the double gob configuration which permits two articles to be formed at one time in each of the various individual sections of a typical glassware forming machine.
  • Each of the blank mold cavities is defined by three cooperating elements as defined in the form of a solid blank body mold 20, an associated intermediate mold 26, and the neck ring mold 36.
  • the intermediate molds 24 and 26 mounted to the mold holder arms 28 and 30 are adapted to clamp the neck ring mold segments in position and in association with the body molds. It should perhaps be noted that when the gobs of molten glass have been fed into the upwardly open blank mold cavities, prior to the configuration depicted in FIG. 3, that the funnel 16 cooperates with the solid body mold in order to receive the gobs of molten glass which will ultimately be formed by the pressing plungers 42 and 44.
  • these plungers 42 and 44 are mounted to an associated supporting structure 14, and will occupy an inactive position such as shown in FIG. 2 when this charge loading step occurs.
  • the funnels move away and means is provided for moving the plunger supporting arm 14 from the position shown in FIG. 2, and for causing these plungers to descend into the positions shown for them in FIG. 3, whereby the gob is formed into relatively heavy walled parisons at the blank side or station of the machine.
  • each of these pressing plungers is individually movable vertically with respect to its associated mounting structure 14.
  • the means for so moving these plungers comprise pistons 46 and 48 to which the plungers are adjustably mounted in order to provide an added degree of freedom for each of the blank structures, and also, in order to provide two active positions for these plungers, one determined by the basic means for moving the plunger supporting arm 14 and a slightly lower pressing position for these plungers as depicted in FIG. 3 whereby the parisons are completely formed in their associated cavities at a slightly later instant of time.
  • the timing for control of the plungers, and also for control of all of the various machine components is derived through the timing drum indicated schematically at 50 in FIG. 3, and air lines associated with each of the various valves in the valve block portion of the timing mechanism provide signals for operation of the various fluid devices in the glassware forming machine.
  • the reader is referred to any of the disclosures in the many patents issued on the timing features of a typical glassware forming machine of this type, and particularly to the U.S. Pat. No. 1,911,119 issued to Ingle in 1933, for a more detailed discussion of these control features in a typical machine section.
  • the plunger supporting structure 14 is operated from and to the position described above by two air cylinders one of which is shown at 52, which actuator 52 has a movable portion 54 connected to one end of a link 56, the other end of said link being connected to a crank arm 58 attached to rock shaft 60.
  • This shaft 60 is shown to best advantage in FIG. 3, and has a lower end which is rotatably supported in a support bearing 62 and the upper end of such shaft 60 carries a flange 64 which is attached to and adapted to rotate a fitting 66.
  • the fitting 66 provides a support for the lower end of a shaft 68, and thus extension and retraction of the movable portion 54 of the actuator 52 causes angular rotation of this shaft 68 in order to move the plunger mechanism between the position shown in FIG. 14 and that depicted in FIG. 3.
  • shaft 68 has a piston 70 provided adjacent its upper end, which piston is splined as shown at 72 in order that rotation of the shaft 68 is also imparted to the housing portion 74 of this actuator.
  • An air line 76 from the timing mechanism 50, provides air under pressure to the lower end of the housing 74, and thereby lower the housing 74 to the position shown and hence lowering the plunger supporting arm 14, to the position shown for it in FIG. 3.
  • An upper support shaft 80 is provided in association with the upper end of the housing 74 in order to further support the housing 74 and to better react the forces generated by the plungers 42 and 44. Finally, the upper end of this support shaft 80 is rotatably supported in a fixed bracket 82 provided in the fixed frame of the machine as indicated generally at 84. Finally, and still with reference to the means for so moving the plungers a cushioning device 90 is provided at the upper surface of the piston 70 and this cushion 90 mates with a corresponding opening defined in the vertically reciprocable housing 74 in order to cushion the downward movement of the plungers 42 and 44. As noted previously individual pistons 46 and 48 are provided in the plunger supporting arm 14 to achieve the pressing movement of the plungers 42 and 44 and to properly form the neck portion of the parisons.
  • a vertically reciprocable rack gear 100 is conventionally provided generally centrally of the machine section, and cooperates with a gear 102 located in centered relationship on a laterally extending shaft, best shown in FIG. 2 and comprising a part of the ring mechanism or hub structure.
  • the said shaft and hub structure rotate the neck ring arms in a conventional fashion from and to the blank sides of the glassware forming machine section.
  • the neck ring arms depicted in the drawings differ from those utilized previously in that the outer end portions thereof are adapted to pivotally support the neck ring structures 38 and 40, and also in that means is provided for retaining these neck ring structures in a particular orientation with respect to the fixed frame of the machine, not only as the parisons are formed at the blank station, but also as the neck ring structure and its associated parisons are transferred from the blank to the blow side of the machine as suggested in FIG. 1.
  • the inner or pivoted ends of the neck ring arms are conventionally mounted to gibs 106 and 108 provided for this purpose on the neck ring structure and more particularly on the splined cylinders 110 and 112 respectively which cylinders are adapted to rotate in response to rotation of the gear 102, that is in response to vertical movement of the rack gear 100.
  • the rack gear 100 is driven from an actuator 114 which actuator in turn is operated through a valving device associated with the timing mechanism 50 of the machine section.
  • These neck ring arms are also movable toward and away one another generally axially with respect to the neck ring hub structure of FIG. 2. Such means is indicated schematically in FIG. 2 and comprises a conventional element of the present combination, and hence need not be described in detail herein.
  • such means includes a pair of axially spaced annular pistons 114 provided on the shaft 104 and splined cylinders 110 and 112 associated with said pistons and adapted to be moved axially in one direction in response to air pressure from the valve timing mechanism 50 and in the opposite direction when such air pressure is cut off, and coil compression springs 116 act between the splined cylinders and axially fixed flanges 118 and 119.
  • said means for transferring the neck ring mold structures 38 and 40 in an orientation which will keep the parisons P, P upright, not only during forming at the blank station, but also during movement to the blow side of the machine preferably comprises mechanical drive means associated with at least one of the neck ring arms and includes an endless chain 130 entrained over the sprockets 132 and 134 carried, respectively, adjacent the pivoted and the free ends of said one neck ring arm 128.
  • This structure is shown to best advantage in FIG. 2 where one of the neck ring mold structures 38 is also depicted as pivotally supported at the free end of said neck ring arm 128 by stub shaft 140.
  • a second stub shaft 142 is aligned with the first such shaft 140 and it pivotally supports the other neck ring structure 40.
  • both neck ring structures are pivotally supported at the free ends of their associated neck ring arms by the aligned stub shafts 140 and 142.
  • Means is preferably provided for continually aligning the neck ring mold structures 38 and 40 with respect to one another on these shafts 140 and 142, and said means comprises a pair of tension springs 150 and 152 extending across and between the neck ring structures 38 and 40 as best shown in FIG. 2. These springs bias the neck ring structures 38 and 40 toward aligned positions with respect to one another especially during return movement of the neck ring mold segments, that is when the neck ring molds are being returned from the blow to the blank side of the machine without any parison supported therebetween. The presence of the parisons P, P will align these neck ring structures during parison transfer movement, but means must be provided during return movement after the parisons are deposited at the blow station.
  • said means further includes a fixed gear 154 carried on the shaft 104 of the neck ring hub structure.
  • the said gear 154 is adapted to mesh with a gear segment 156 provided on a rock shaft 158, which rock shaft also serves to support the sprocket 132 associated with the inner or pivoted end of the neck ring arm 128.
  • An outer gear or idler gear 160 is provided at the free or outer end of the neck ring arm on the stub shaft 140, and said gear 160 meshes with a gear 162 (best shown in FIG. 2) located on the same shaft 138 which carries the outer sprocket 134 mentioned previously.
  • the fixed gear 154 on shaft 104 causes clockwise rotation of the gear segment 156 with the result that the chain 130 rotates in such a direction as to cause similar clockwise rotation of sprocket 134 corresponding to that of its associated sprocket 132 with the result that gear 162 also rotates clockwise causing gear 160 to rotate counterclockwise and through an angular displacement equal but opposite to that of the neck ring arm itself. Since the gear 160 is carried by stub shaft 140 it follows that the neck ring structure 38 will also rotate with respect to the arm and thereby remain in its horizontal orientation as depicted in FIG. 1 as the arm so rotates.
